In short, the clock uses the outer blades of an asymmetrical fan like watch hands. The shortest blade represents the hour hand, and the longest blade represents the minute hand. As time passes, the hands rotate around an axis, making the fan expand and contract with the seductive rhythm of a hypnotist’s charm.

Conceptually, this almost identical to Studio Ve’s fan clock, which we wrote about late last year. A couple of differences: The Spire Clock registers seconds by flashing LEDs in the tip of the fan’s 24 blades. It’s also got a handle, which houses all the mechanics that make the thing tick.
